Explanation

This JSON snippet shows how to include a Remote MCP Tool configuration in the `tools` array of a request. It specifies the `server_url` and optionally `allowed_tools` to define which tools from the MCP server are accessible.

What it does and when to use it

This JSON configuration demonstrates how to set up a Remote MCP Tool within a Grok request. It requires the MCP server's URL and can optionally list specific tools to be made available to the model.

Why it works

The `tools` array is where Grok expects tool configurations. Specifying `type: "remote_mcp"` and providing the necessary parameters enables the integration.

When not to use it

When not using Remote MCP Tools or when configuring tools through a different mechanism.
